Great machine verypowerful

Very happy with performance size and power. It starts right up everytime

Cat pump Honda motor say no more

Reliable plenty of power will last for years my first one lasted 15 years and it still runs. Remember your pump is only as good as the water pressure that you have feeding it

Does what it is supposed to do

Overall it's a good pressure washer. Have approx 5 hrs on it. I did add an induction type hour meter for maintenance intervals.

The Honda motor and CAT pump are great. Starts VERY easy with the nozzle removed and the trigger handle wedged open. Remember to crank down on the unloader to get the pressure you want.

The frame, not so much. Tends to 'walk' when using. Within the 5 hrs, the 'feet' were worn down. I ended up pulling the feet off my 20+ year old pressure washer (that never wore out) and put them on the Simpson. Also used some Destaco type push/pull clamps to add brakes to the wheels so it won't move around. May end up adding some vibration isolators between the engine and frame like my old Craftsman pressure washer had.

Used some 1.25" galv conduit and raised the handle up around 12". Added another hose hanger and a basket to put accessories.

I'd buy it again at the price point.

I never knew pressure washing could be so easy!

I waited a long time to buy this particular pressure washer. Honda motor with the Cat pump is a dream to clean with. Power to spare. So far, I could not be happier with my choice. Thank you Simpson for making an American made product!
